Correlation, not causation:

> Laboratory studies revealed elevated creatinine kinase level indicative of rhabdomyolysis.

Rhabdomyolysis is associated with a range of medications, drugs and toxins.

Many medications increase the risk of rhabdomyolysis.[12] The most important ones are:[4][9][11]

    Statins and fibrates, both used for elevated cholesterol, especially in combination; cerivastatin (Baycol) was withdrawn in 2001 after numerous reports of rhabdomyolysis.[13] Other statins have a small risk of 0.44 cases per 10,000 person-years.[8] Previous chronic kidney disease and hypothyroidism increase the risk of myopathy due to statins. It is also more common in the elderly, those who are severely disabled, and when statins are used in combination with particular other medicines, such as ciclosporin.[13][8]
    Antipsychotic medications may cause neuroleptic malignant syndrome, which can cause severe muscle rigidity with rhabdomyolysis and hyperpyrexia
    Neuromuscular blocking agents used in anesthesia may result in malignant hyperthermia, also associated with rhabdomyolysis
    Medications that cause serotonin syndrome, such as SSRIs
    Medications that interfere with potassium levels, such as diuretics

Poisons linked to rhabdomyolysis are heavy metals and venom from insects or snakes.[4] Hemlock may cause rhabdomyolysis, either directly or after eating quail that have fed on it.[4][11] Fungi such as Russula subnigricans and Tricholoma equestre are known to cause rhabdomyolysis.[14] Haff disease is rhabdomyolysis after consuming fish; a toxic cause is suspected but has not been proven.[15]

Drugs of recreational use, including: alcohol, amphetamine, cocaine, heroin, ketamine and MDMA (ecstasy)[4][11]

Yes, that is because they both effect serotonin and serotonin receptor density.
